Can anyone enlighten me as to why,
often, when I receive an e-mail from my ISP Wanadoo (and they are genuinely bona-fide messages offering me Broadband etc,) Avast gives me an on-screen warning that it might be dangerous? It’s never done it with other, more potentially suspicious messages, only these which are obviously respectable,genuine and completely clean.
Maybe your email Heuristics must be corrected to allow it… Use less strengh on Heuristics (sensibility).
You can add URL to the permited ones if this is the problem.
Thanks for the prompt reply…I’m a relative novice,so could you explain what I need to do to alter the Heuristics?
Left click the ‘a’ blue icon on the system tray.
Choose Internet Mail provider at left and click on Customize.
Go to the Heuristics tab and choose a lower level on the slider.
Do the same for the MS Outlook plugin if you use it…
See if the email is taken as a legitimic one.
Oh, there is the URL permited option too…
I’m sure that this warning contained more information and I think that it related to iFrame, this is normally only used in web pages to import data, typically adverts.
AN iFrame in an email can import external data and has the potential to run a script or program, that can have great potential to do harm on your system. Wanadon’t seem to use this to deliver ad content in emails.
Unfortunately the iFrame check is in every level of heuristics, so lowering it won’t work. However, you are only getting a warning and you can choose to over ride it if you believe it to be legitimate. It might be legitimate but it could also be classed as Spam if you didn’t opt-in to receive this type of email.
Me I would never accept an email with iFrame tags, legitimate or otherwise, the potential is too great and from email addresses can be forged.
There is a way not to check the iFrame tag, if this was what the warning was about (but this I feel is a risk not worth taking), you need to set the heuristics to custom and click the Customize… button here you will see the iFrame local and remote checks.
